The Doctor -- though we'd always be in danger from aliens, if he were real.
And we all know which incarnation...
Han Solo - he'd be good craic at a dinner party.
Rygel from Farscape
I'd go for Stark and Aeryn too!
Ohh yes, good point. I love Aeryn and you mentioning Stark made me realise I neglected my favourite Farscape crew member: Zhaan. I would love her to be around!
